[ClusterLabs] ethmonitor is not working

I have two node active/passive setup. This is my configuration:

#service firewalld stop
#vi /etc/hosts --> (Node1) / (Node2)
------------- Private Network (Direct connect)
#systemctl start pcsd.service
#systemctl enable pcsd.service
#passwd hacluster --> define pw
#pcs cluster auth Node1 Node2
#pcs setup --name Cluster Node1 Node2
#pcs cluster start -all
#pcs property set stonith-enabled=false
#pcs resource create ClusterIP ocf:heartbeat:IPaddr2 ip=
cidr_netmask=32 op monitor interval=30s
#pcs resource defaults resource-stickiness=100
#pcs resource create ens192-monitor ethmonitor interface=ens192 --clone
#pcs constraint location ClusterIP rule score=-INFINITY ethmonitor-ens192
ne 1

My goal is to have two interfaces, service network(ens192) and heartbeat
network(ens224). Based on my research, ethmonitor is used to monitor the
interface via pacemaker, if there's a failed link, resources will failover
to other Node. My problem is no error were prompted via pcs status,
resource does not failover and service(ClusterIP) goes down.

Testing scenario:
1. Disconnected physicall Link of Node1 ----> No error appears on pcs
status and ClusterIP is not reachable as failover to other node does not

Any ideas? Is this a bug? Are there any missing configurations?
